To all whom it may concern:

Be it known that I, HENRY G. VOIGHT, a citizen of the United States,residin in New Britain, county of Hartford and tate of Connecticut, haveinvented certain new and useful Improvements in Locks, of

which the following is a full, clear, and exact description. 7

This invention relates to looks, and more particularly to a lockdesigned to look a gearshift lever so that the lever cannot be vmoved byan unauthorized person after it has been locked in its neutral position.

The object of this invention is to provide a locking device consistingof a pivoted latch and key-controlled means for operating the latch. y

' A more specific object of this invention is to provide means forlocking a gear shift lever of an automobile to the slotted guidingbracket with which these levers are usually provided, so that anunauthorized person cannot shift the gears of the automobile,

and' hence cannot operate the automobile.

In'the drawings, 10 designates a gear shift lever adapted to shift the;gears of an automobile. A slotted guiding bracket with which theselevers are commonly provided is designated generally by the numeral 11.The locking means which I have devised for locking the lever 10relatively to its guiding bracket '11 consists of a latch 12 pivotedupon the lever 10 by means of a bolt on pin 13, a washer 14 preferablybe-. ing provided between the outer face of the latch and the head ofthe bolt. The width of the latch 12 is preferably slightly less when thelatch 12, which is pivoted on this pin, is moved to substantiallya'horizontalj position, the lower edge of the latch'will clear thecurved upper face of the bracket 11, as shown in full lines in Fig. 1;but

when the latch'is lowered, as indicated in dotted lines in Fig. 1, theouter end of the" latch will snuglyffit in one of'the slots 11 of thebracket 11, the arrangement 'being such that while the latch 12 has itsouter end pos tioned in oneof the slotsl-l, as indicated in dotted linesin Fig. 1, the lever 10 cannot be moved to shift the gears operated bythis lever. The upper face of the latch 12 1s preferably provided with aslotted lug 12", the object of which will be hereinafter described.

In order that the latch 12 may be locked in either of the two positionsindicated in Fig.1, I provide a latch-operating rod 15, the lower end ofwhich is preferably provided with a reduced portion that is inserted intheslot formed in the lug 12" above re ferred to. The reduced portionofthis rod lsplvotally secured to the lug'12 by means of a pin 16.- Theupper end of the rod .15 is provided with a notch 17 the object of whichwill be hereinafter described.

Mounted upon the lever 10 is a lock case 18, which is preferably securedto the lever 1 by means of rivets 19. H The case-1s is so posit-ionedupon the lever 10 that it receives and incloses the upper end of the rod15, which upper end extends through a rod-receiving opening formed inthe lower face of the case 18.

Inside of the case 18 is mounted a pin' tumbler lock 20. This lock isprovided with a air of projecting lugs 21, having drill ho cs 22 formedtherein. The lock 20 is provided with the usual pin tumblers 24 operat-The lock is also provided with I which 15 secured to the end of the keybarrel 7 by screws or similar securing means 28. The

outer face-of the eccentric disk 26 has a circular groove formed thereinconcentric with 'the'opening formed in the disk, in which the small disk27 is seated, as shown in Fig. 8. The operating means between the keybarrel 25and the eccentric disk 26 consists of 'a pin 28" rigidlymounted in the projecting 30.

" erally therefrom. This pm 28" cotiperates t with opposite walls 29formed upon the inend" of the key'barre-l 25 and extending lat- I nerface of the disk 26. A clearance space Ffor the pin-is provided in thedisk 26 by Ffaceof this disk. venientlybe formed upon the disk bycutting a slot 31 across the inner face thereof.

formin the arc-like roove 30 in the inner The walls 29 may con- Themeans just described forms what is known as a lazy connection betweenthe key barrel 25 :and the eccentric disk 26, the arrangement being suchthat the key barrel ,ma be rotated through a complete circle,

-while'the, diskwill be swung through only ,ap roximately one-half ofthis circle. In

. or er to limit the angle through which the disk 26 -maybe swung, I 7provide a lug 32 formed upon the lock 20, and having an *endprojectingbeyond the inner end of this look, this projectlng end beingso positioned that it contacts with an edge ofthe disk 26 or with a wallof the slot 31 formed in this disk,

as shown in Figs. 5 and 6, thus limitingthe anglp through'which thisdisk may be roxtate I The pin tumbler lock 20 is mounted within the case18 and is rigidly secured thereto end of the key plug 25 projectsthrough a circular opening formed in the outer face of the casinglS, asshown in Figs. 1, 2 and 3.

When the lock 20 is mounted within the case 18, the parts are sopositioned that the outer that the latch 12 will have itsouter endtioned, the lever 10 will be locked in its neui tral position and thesame cannotbe shifted to operate the gears controlled thereby.

2. Ina

above referred to, formed in the rod 15, the arrangement being suchthat'when the disk 26 is rotated about its eccentric mounting upon thekey plug '25 by means of the key 34, the bolt 15 will be moved in alongitudinal direction to either raise or lower the latch 12 accordingto the direction in which the key barrel is rotated. By providing thelazy connection above referred to between the key plug 25 and the disk26, it will be seen that the key 3 1 may be removed from its lock whenthe disk 26 is moved toeither of the two positions indicated in Fig. 5that the position shown in Fig. 4. The key 3 1 is S.

then inserted in its lock and the key barrel 25 is rotated to operatethe bolt 15 so that thelatch 12 will be moved to the positionindicatedin dotted lines in Fig.1, thatfis,so

moved into one of the slots ll iof the bracket 11. I It will, therefore,be seen that while the latch 12 has its outer 'end in engagement withone of the slots .just men- I have not attempted to describe the modi- V'fications of the construction which maybe adopted without departingfromthe scopev of the invention.

I do not claim herein the specificdrivin connection between theeccentricidisk an the key barrel as this structure is claimed in What Iclaimis: 1. In. combinatioma bracket, a lever comyPatent'No;1,293,258granted February 1.05
